Circles ncert solutions Chapter 10 Exercise 10.2 Question 2
2. If, TP and TQ are the two tangents to a circle with centre O so that
then
is equal to:
(A)
(B)
(C)
(D)
Solution:
We know that tangent is always perpendicular to the radius of circle. Therefore,
and
are both
because TP and TQ are tangents to the circle and OP and OQ are radii. (1)
In Quadrilateral TPOQ
(Sum of interior angles of Quadrilateral is equal to
)
Therefore, answer is (B)
